Have just bought a Link out of an Rs liberty and want to place in my 95 ej20tt. The person I purchased it of said to run the antilag I would have to have two switches. One to turn the antilag on and one for the rotational idle. He also said this would run of my aircon to up the rpm. Also he said something about another fuel solinoid, say of a VN commodore. Could some one explain this a little clearer for me maybe with some diagrams thanks Sean.
